It is because these books of power hold the truth that makes men free, working thoughts that perish never, that they live when the tongues in which they speak are dead. Books of power which transmit the spiritual life of the race keep the self-same spirit through all the transmigrations of speech. The scriptures of the race, no less than the scriptures of religion, enjoy a pentecostal gift of tongues, and are heard by every man in his own language. Where such books are few in number, which a shelf or two will hold, there is a liberal education, and no elective course which permits their exclusion offers intellectual salvation. Some such books every race has found in its own literature as it reached the full stature of universal humanity, as our own English-speaking race, well-nigh within this generation, has discovered in adding Shakespeare to our general schooling. By the production of such books of power nations are justly measured. This is the wisdom which keepeth a city from destruction. The ship of state, however weighted with worldly wealth, moves a trackless keel through the waters of history unless some poet wings its course with "the proud, full sail of his great verse." We have all heard to-day from one whose lifelong devotion has raised him to the foremost rank of scholarship. "Weave a circle around him thrice And close your eyes with holy dread, For he on honey-dew hath fed And drunk the milk of Paradise." The study of such books is possible without any aid or apparatus whatever; so near is the diviner of letters to every one of us. But the first office which the library discharges in a university is in providing the limitless and manifold interpretation which the ages have builded about these great books of power. Better than all other books as are the books of power when read without study, they are infinitely bettered by all study. The literature of interpretation is only second in value to the literature of inspiration. The study even of books of power tends to become scholastic, narrow, provincial, letterwise, and spiritually dead, unless it is quickened and corrected by the fruits of the entire field of critical science. For lack of this more than one sacred book has met a fate which makes one feel, as well kill a book as give it a good name. Even in the teaching of books of power--which of all teaching needs but a soul and the book to awake eternity--the scholar is saved from himself by the library. He learns that with all the inspired prophets of the race no scripture is of private interpretation, that only time unlocks the weaving of these deeper oracles of humanity, because they spake not of themselves, but for the spirit of man. Nor need we fear that they will be smothered by their interpretation. The mountains bear easily the weight of forests they uprear, and at the last and highest, no tree ascends above the snow-line of eternal thought.
